The former Googler also already written two books — "Lean In" and "Option B" — on her experiences balancing her high-powered job with her personal life, along with the insight she's gleaned along the way.

Here's a look into the productive daily schedule of Facebook COO Sheryl Sandberg:

Sandberg is an early riser who plans her morning around dropping her two children off at school. She often arrives at work around 7 a.m., according to Fast Company.

At the start of every leadership meeting, participants can go around the table and discuss their "emotional and professional state," according to Bloomberg.

In a Quora post, Sandberg credited Facebook CEO Mark Zuckerberg with helping the entire company to conduct more efficient meetings: "We try to be clear about our goal when we sit down for a meeting — are we in the room to make a decision or to have a discussion?"

The Facebook COO revealed that her work has been a comfort since the sudden death of her husband Dave Goldberg in 2015: "Facebook is helping me get through what has been the hardest year of my life."

No matter how busy the Facebook COO is, she still makes certain to leave work by 5:30 p.m. sharp.

Before her husband's death, the family would eat dinner together every evening and "share the best and worst moments of our day," she wrote in the New York Times. It's a tradition that Sandberg continues today with her children.

Today, Sandberg tends to turn in early. She even supported Arianna Huffington's sleep hygiene campaign, calling for business leaders to encourage their employees to get more shut-eye.

In a 2015 Quora post, she wrote that she was speaking on the phone one evening with Zuckerberg, and told him she would be going to bed at 9:30 p.m. He became worried that she was feeling sick. "I explained that with two young children, 9:30 p.m. was often my normal bed time," Sandberg wrote.
